Your IP address: No Network Connected

For two weeks while visiting family in China, the BitDefender VPN worked fine. Today, however, it's been completely changed and no longer recognizes an internet connection. I obviously have one, or I wouldn't be able to type this. I've tried ever work around I can think of, but nothing works. Suggestions? Like, how to roll back the update? 90% of my work sites are unreachable since this update, and I really need to be able to access them. I still have two months in China before returning to Florida.
